Title:
METHOD FOR PURIFICATION OF SUBSTANCES CONTAMINATED WITH ORGANIC CHEMICALS
Document Type and Number:
WIPO Patent Application WO/2007/074776
Kind Code:
A1
Abstract:
The invention aims at providing a simple and easy method by which many kinds of
organic chemicals (contaminants) can be efficiently decomposed in a short time
and separated and recovered as insoluble matter. Water or soil contaminated
with organic chemicals can be purified by adding a specific metal compound and
an ionic transition metal compound to the water or soil, irradiating the resulting
water or soil with light to decompose the organic chemicals efficiently into
insoluble matter, and separating and recovering the resulting harmless matter.
